Overview

Padded by a thick rubber foot, this stainless steel knock box is not moving anywhere when knocked into! It stays in place and you don’t have to worry about scratching your counter top. The stylish j curve cut profile allows you to knock your coffee grounds into the box without the worry of coffee splashing all over the counter. The knock bar is encased in rubber tubing to protect your portafilter when knocking. And, the knock bar is held in place by two rubber gaskets and is easily lifted out for cleaning. A huge bonus is that the entire casing is dishwasher safe!

Available in 2 sizes:

Standard: 6.25"H x 4.5"W x 4.75"D

Extra Large: 8.25"H x 7.5"W x 5.75"D

Questions

I really like the design and the size of the box. The bar however, is a different story. I ended up having to buy a replacement bar because the balls unscrew very easily and ended up being thrown out accidentally.

What's Best About this Product?
The design: back lip hight to keep grounds inside.

Some Helpful Tips For Using this Product
Make sure the balls are screwed tightly at all times

So far so good with this knock box! I was pleasantly surprised that the housing is polished steel and not white, as it appears in the pictures. I don't know if the stock photos they're using have the protective cling wrap on them or not, but it looks better as a polished steel than the more retro painted white box I thought I was getting, IMO. The rubber base is very substantial and solid. The grommets on the bar do seem to be a little on the flimsy side, as others have mentioned, but I'm not too concerned about them wearing out or finding replacements down the road.

What's Best About this Product?
Polished steel housing looks fantastic. The rubber footing is also very stable and solid.

Some Helpful Tips For Using this Product
You have to play with the angle you knock at to make sure you don't get any stray grounds coming out the cross bar holes.

Excellent knock box

Overall Rating:

This is an excellent knock box. Sealed and never licks. The rubber tube covering needs to be replaced at some point. Just go down to an auto parts supply house an buy a small amount of rubber fuel line; it works great and is very durable. Be sure to take the bar with you for the correct size. Less then $2 per foot.

What's Best About this Product?
Great size

Great knock box!

Overall Rating:

Granted, this is really my first knock box, but I like the high back and side walls to prevent splatter from getting on the counter. The rubber base is nice. Overall, not much to complain about. It does its job well.

What's Best About this Product?
High back and side walls to contain splatter.

Some Helpful Tips For Using this Product
Get the larger version. I should have gotten the larger version. Personally, the smaller one requires dumping more often than I'd like.

A must have item

Overall Rating:

I purchased the larger box and it works great. With my other cheap espresso machines it was not hard to rinse out the little portafilter. Now that I am using a Expobar with the E61 grouphead, I really needed a knock box to dislodge the coffee. This unit works great and is easy to clean. Thanks to the other reviewers for advice on the grommet issue. I will try the hardware store for a fix when the time comes.

What's Best About this Product?
Great build quality and should last for years. Easy to clean.

Some Helpful Tips For Using this Product
Whacking the heck out of the portafilter to get some of the more difficult pucks out has got to be hard on any knock box. Expect to have maintenance on all knock boxes eventually.

When I got into the espresso/grinding/roasting game, I initially did not have anywhere to knock the grounds. I thought that I could just knock them into my small sink holding the disposal, but this was not a good idea since I was banging the portafilter against the granite. I found this box, and it works like a charm. PLUS, all my friends are amazed that I have a knock box "just like a real barrista." Based on previous reviews, I went on and ordered a second bar expecting this one to fail. I've now had it for 13 months with no problems. Sooner or later, I'm sure the O rings will break, but I have a back up ready to go. This is a simple device that works well and completes your coffee bar.

In use for some 8 years now and, yes, the grommets and tubing are the design weak points; but we appreciate the fact that the coffee puck is better contained after knocking than in a traditional open style, especially with limited counter space. When the grommets and tubing go--and they will go--you can either purchase the entire assembly (which includes another bar) from WWL or go to a hardware store and purchase 3/8" neopreme rubber grommets @ $0.90+ ea. (I keep a few on hand) and a length (usu. by the foot) of clear vinyl tubing 1/2" X 5/16" (exterior X interior diameters) @ $0.50+ a foot, which you then can cut to a 3-inch length (and thereby have three more replacements when this one goes).
On a purely aesthetic note, this box looks great with our 8-year-old Expobar Office Lever and doserless Rancilio "Rocky."
